[. . . ] Manual Rev 1. 0. 4 March 7, 2005 OWNER'S MANUAL X. 200 Digital X Bus Important Safety Instructions 1. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat. Do not defeat the safety purpose of the polarized or grounding-type plug. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet. [. . . ] Gate A gate is used to duck or mute a channel when the signal level drops below a certain point. This can reduce the overall noise level in your mix by muting unused or noisy channels. The gate is represented graphically by a diagonal line across an X-Y coordinate display. The horizontal axis represents the input signal level to the gate, and the vertical axis represents the output signal level from the gate. When the input signal level is below the threshold setting for the gate, there is no output and the red indicating LED in the gate window lights. When the input signal level is above the threshold, the signal passes through the gate unaffected. There are five controls for the gate along the bottom edge of the window. Note: When we say the gate opens, it means the gate is not acting on the signal and the signal is allowed to pass. Threshold · Determines the level at which the gate acts on the incoming signal. Attack · Determines how fast the gate opens once the threshold has been exceeded. Hold · This determines how long the gate remains open after the input signal has fallen below, and remains below, the threshold before closing. It is calibrated in milliseconds, ranging from 20 ms to 1000 ms (1 second). Release · Determines how fast the gate closes after the hold time has expired, once the signal falls below the threshold. It is calibrated in milliseconds, ranging from 10 ms to 1000 ms (1 second). · · · Owner's Manual 41 Digital X Bus Range · Determines the amount of gain reduction applied to the signal once the signal level drops below the threshold. It is calibrated in percent, ranging from 0% (no attenuation) to 100% (full attenuation). Key (Trigger) Input · · Uses the signal from another source to trigger the dynamics for a channel. · Touch the EQ window below the drop-down box to turn on the key input EQ (the background of the EQ graph lights). · The key input EQ filters the key input signal prior to triggering the gate. It is a peaking filter, and allows you to tighten the trigger signal to a narrow band of frequencies. · There are two controls for the key input EQ, Frequency and Q. Use the V-Pots below the graphic representation of the knobs to adjust the controls. Surround (Ctrl+6) The SURROUND window offers precise control over image positioning in any mixing panorama along with individual subwoofer level and depth of center control. Surround position control is available from the control surface by using the individual channel PAN L/R and PAN F/B V-Pot controls.
